"ooLLArsIBLn FILLING PLUG.

Application filed August 4, 1922. Serial No. 579,735.

T 0 all whom it may concern:

Be it known that I, WILLIAM H. RICH- Aims, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Collapsible Filling Plugs, of which the following is a specification.

This invention relates to collapsible filling plugs and more particularly to filling plugs for liquid containers although its uses in other connections are apparent.

It is an object of this invention to provide a filling plug, funnel and cover combined which will be eflicient and simple of opera tion and will be capable of being opened or closed in an instant. To these ends means are provided whereby the funnel is pulled out and the cover opened, ready for the filling operation, in one continuous movement. So too, in closing the device one movement only is required.

It is a further object to provide a collapsible funnel means in conjunction with the usual filling plug and so connected thereto that the container may be filled either with or without pulling out, i. e. extending the funnel.

It is a further object to so arrange the collapsible funnel with a filling plug that it may be used for automobile or airplane radiators.

Further objects will be obvious from the claims and from the description of the drawing in which Figure 1 is a vertical section of the invention as attached to the filling plug of an automobile radiator and taken on line II of Figure 3.

Figure 2 is a similar view in expanded section taken at right angles to the view of Figure 1.

Figure 3 is a top plan view of a preferred embodiment of the invention and Figure 4: is a part of the device in section showing the cover latching means.

Referring to the parts in detail, 2 designates an ordinary radiator filling plug which is provided with a flanged member 4 in the shape of an oval cup and which is also provided with screw threads 6 or other means whereby it may be attached to the radiator, in this case, of an automobile. A circular or oval (not shown) collapsible cup 8 composed of a plurality of telescopingsections,

' tapered inwardly as shown at 10 in order to prevent splashing whilelfilling the-radiator.

As shown, the plug 2 is'beaded-over the collar 10 as at 12 to secure the collar thereon. The plug 2 is provided with interiorly projecting flanges 14c for a purpose later described. Drain holes 8 are provided in the support 4.

The cup 8 is provided with a cover 16, hinged to the top section as at 18 and a reenforcing ring of wire or suitable material 20 completely encircles the top section.

Thelatching means shown in Figure 4 comprises a latch member 22 secured to a spring 24: riveted or otherwise secured to the outside section of the cup at 26. The latch 22 is provided with a detent 28 which permits the latch to snap over the cover 16 and the cover is recessed as at 30 to allow the latch to pass therethrough. The cup guard and support at may be recessed as at 30 for a similar purpose.

The cover is provided with a handle 32 attached to a spindle 34 attached in turn to cover 16 by flange 36. The spindle 34 has riveted thereto at its lower end a spring clip 38 which upon turning the handle 32 1 is engaged or disengaged at its ends with flanges 14, aforementioned.

It will be seen that to prepare to fill the container through my device, that it is only necessary to give handle 32 a small rotational movement, lift up on it pulling the telescoping segments of the cup out until they lock and then to release the cover 16 by depressing lever 22, so that it may be swung back to the dotted line position 40 of Figure 1.

I claim:

1. A collapsible filling device comprising, a collapsible cup, a combined filling pipe and cup container, a cover for said cup, means whereby said cup may be collapsed and locked or unlocked and extended and means whereby said cover may be subsequently opened upon the extension of said cup.

2. A device of the character described comprising, a filling pipe adapted to position a telescopic funnel thereon, a tunnel of such character thereon, a guard for said funnel exteriorly adjacent said filling pipe and a cover for said funnel.

3. A device of the character described comprising, a filling pipe adapted to position a collapsible tunnel thereon, a tunnel of such character thereon, a guard for said funnel exteriorly adjacent said filling pipe and integral therewith, a cover for said funnel, means to lock and unlock said funnel to and from said pipe when said funnel is collapsed and means to unlocksaid cover from said funnel subsequently to unlocking said funnel.

4. In a device of the character described, a filling pipe and cup shaped guard adjacent thereto, a collapsible funnel between said guard and pipe and positioned on a downwardly converging tapered collar attached securing said tunnel to said tube and support.

6. In. combination with a radiator having a filling tube, of a funnel support on the outer side of said tube. a collapsible filling funnel on the outside of said tube having a cover and adapted to rest on said support when collapsed, means for releasably securing said tunnel to said tube and means whereby said cover may be relcasably secured to said funnel.

In testimony whereof I aflix my signature.
